Jungheinrich Eje 120 Error Code 4372 Work

The error occurs because the "neutral zone" window on the tiller head potentiometer is too narrow, causing the system to misread the tiller position.

Request a firmware update via the official proprietary diagnostic link ( Jungheinrich Incado ).

Before diving into code 4372, it is crucial to understand what you are working with. The EJE 120 uses a CAN-bus (Controller Area Network) system. The main controller (often called the "Traction Controller" or "Vehicle Control Unit - VCU") communicates with several sub-components: jungheinrich eje 120 error code 4372 work

: Ensure the battery is holding a charge under load, as low voltage can sometimes cause erratic sensor readings.

Follow this systematic troubleshooting approach to isolate, diagnose, and repair the root cause of the error. 1. Perform a Hard Reset and Visual Check The error occurs because the "neutral zone" window
